Gears

Temperature variations between operation and standstill, the volume of air is constantly changing in a transmission. Sucked, moist ambient air reduces the service life of a gear oil significantly. Furthermore, leads moisture in the housing to corrosion with particle abrasion and thus damage to the transmission.Good gear ventilation filters prevent the entry of humidity in the "breathing" of the transmission. GIEBEL Adsorber® are special gear ventilation water filters for ventilation. So this breathing dryers are used for example in coastal areas, offshore, in tropical regions, and underground with success. You can find all information on gear ventilation on https://www.giebel-adsorber.de/en/applications/gears.
